LANTERN,

Application filed February 21, 1927. serial, 110.169,?47.

This invention relates to lamps or lanterns or like burners, andespecially to thoseot the type in which a combustible liquid. such asgasoline is forced upward through. atube, from a well burner, by fluidpressure maintained in the well upon the surface of the liquid.

In lanterns of this type commonly used heretotorethe well has beenprovided with a filling hole substantially at the top of the well forthe reception of the liquid fuel. The construction of the well at'thefilling hole has been such that a spouted can or a tunnel has beenrequired for satisfactory filling of the lantern without spilling of theliquid.

A further cause of annoyance has been that unless great care is takenthewell is filled so full that it is necessary to pour out some of theliquid in order to provide the necessary volume of air in the well toafford from the time of the filling an adequate cushion of air to avoidthe necessity of "frequently pumping air into the well to maintain asuitable pressure therein. I

Another consideration. that has operated against the popularity ofthistype of lantern, which usually employs. a mantle andrequiresfrequent replacement oithe mantle andcleaning or replacement of thegenerator tube or other. parts, has been the matter of having at handwhen needed the necessary spare parts or tools for mounting them or forcleaning purposes. I

Such lanterns also have not been well adapted for simply hanging from anail driven into a wall because of heating of the wall and tilting ofthe lantern.

The misplacement and loss of filler caps is another evil in connectionwith the lanterns of the prior art, which may be the source ofsubstantial danger of explosion in the case of a gasoline lantern, inwhich the filler ca should always be in place when the lantern 1slighted.

My chief objects are to obviate these several objections, which Iaccomplish with very little modification of the structure, providing atthe same time a fuel-well structure adapted to withstand hard usage.

Of the accompanying drawings:

Fig. 1 is an elevation, with parts broken away and in section, of alantern embodying my invention in its preferred form.

Fig. 2 is an elevation of the same on a smaller scale, supported invertical position by a nail driven into a wall, the lantern sosupportedin filling position, also being there shown in dotted lines.

Fig; 3 1s a planview of an flCltlltlOllal bOtf tom closure or. floormember for the base of the well, witlrspare parts and tools mountedthereon.

Referring to the drawings, the upper por tion oi the lanternmay be ofwellknown and attachment to the lantern, a bail-like strut i2 having. anextensive straight reach 12 in its arch portion, so that the lantern maybe supported with stability in vertical position at a distance from awall 13, as shown inFig. 2, by hooking the bail upona nail 1 L driveninto the wall and allowing the strut 12 todrop into position as shown,to space the lantern from the wall, the strut preferably being sointerlinkedi-vith the baihas there shown, that the hinge-loops oi thestrut will contact the bail to stop the strut inhorizontal position; andprevent accidental downwardslipping oil? the strut. on the wall.

The bail and, strut are adapted to permit the lantern to be turnedupside down, to rest over-center against the wall, in the dotted lineposition of Fig. 52;, while the bail and strut remain in theirsupporting positions.

The well 15 of the lantern is provided with the usual air-pump 16, feedtube 17, and stopvalve 17 therefoigbut is without the usual fillingholeat the top of the well.

The bottom wall or floor 18 oi the well is of obtuse conical form,rising to itscenter, where it is provided with an internally threadedfilling-port member 19, which may have a strainer 20 mounted thereon,and is adapted to receive a threaded filling-port plug 21 provided witha gasket 22.

The outer margin of the floor l8 joins the side wall of the well in adownwardly proj ecting cylindrical base flange 23 having preferably aplurality of bayonet-lock studs 24, 24 projecting from its inner face.

Fitted in the base flange 23 of the well is the annular wall portion ofa cup-shaped floor member 25 formed with bayonet slots 26, 26 adaptingit to be interlocked upon the studs 24, the tloor member 25being formedat its outer margin with a folded annular flange portion 27 projectingoutward beyond the base flange 23 of the well, so that the force ofbumps sustained by the flange 27 will be transmitted through the floormember 25 to its opposite side and there received over a considerablearea by the cylindrical contacting face of the base flange 23, wherebylocal denting and opening of the seam oi the base flange 23 is avoided,notwithstanding the conical form of the floor 18 of the Well. Theprojecting fian e 27 of the floor member also facilitates the removal ofthe floor member trom the lantern.

Within it the cup-shaped floor member 25 has secured to its upper facespring clips 28, 28, 29, 29 and 30 for retaining in fixed positionsthereon a supply of mantles 31, 31, an extra generator tube 82, atipcleaner 33 and a wrench 3a.

In the filling of the lanteri'i, the stop-valve 17 being closed, thelantern may be supported in an inverted position, as shown in dottedlines in Fig. 2, by means oi: the bail 10 and strut 12, so that thedifficulty of holding the lantern inverted by hand is avoided.

The floor member 25 being removed by disengaging it from the bayonetlockstuds 24:, the filling-port plug 21 is removed and the gasoline or likefuel is poured into the inverted well through the filling-port, thefloor member 18 of the well serving as a tunnel, until the liquid sorises as to be visible in the port member 19. The conical form of thefloor member 18 assures that when the well is filled to that level thewell will still contain, in an annular space about the filling-portmember 19, a proper quantity of air to permit the building up of anadequate initial air cushion by means of the air pump 16 when theclosure-plug 21 is screwed in place and the lantern turned back to itsupright position.

The floor member 25 may be remouuted in the lantern before the latter isso turned back, the spring clips holding the spare parts and tools inplace thereon.

lviodifications are possible within the scope of my invention as definedin the appended claims.

I claim:

1. A lantern comprising a well portion having a filling port in itsbottom Wall, a bail hinged on the lantern, and a strut member mounted onthe bail for laterally propping the bail, the bail and the strut beingso shaped as to permit the lantern to be turned about the hinge axis ofthe bail to inverted position while the bail and the strut are insupporting position.

2. A lantern as defined in claim 1 in which the bail and the strut areso proportioned in relation to the rest of the lantern that when theouter'ends of the bail and the strut are substantially in the samevertical plane at the face of a support such as a wall against which thelantern is hung the body of the lantern when inverted will lean instable condition against'the said support, in a slightly overcenterposition with relation to the hinge axis of the bail.

8. A lantern comprising a well portion having a filling port in itsbottom wall, the said wall being so formed as to provide a funnel forthe port when the lantern is inverted, and an additional floor memberdetachably secured to the well portion of the lantern and with thebottom wall thereof defining a chamber, the floor member being fittedtelescopically into the said well portion and formed with an annularbase flange projecting laterally of the lantern beyond the said wellportion.

at. In a lantern the combination of a hinged bail, a strut member hingedto the bail and eoacting means on the bail and strut member for stoppingthe latter in its hinging movement at a determinate angle to the bail.

5. In a lantern the combination of a hinged bail and a strut member somounted on the bail as to constitute a lateral prop for the bail whenthe bail is hooked upon a support.

In witness whereof I have hereunto set my hand this 19th day ofFebruary, 1927.

JOHN R. GAMMETER.
